High-efficiency rotational tracking components engineered for industrial concentrated solar heliostats and solar tracking equipment.
Established in 2022, Jiangsu Manchen Transmission Technology Co., Ltd. is a professional manufacturing enterprise integrating cutting-edge design, intensive research and development, manufacturing, and comprehensive sales channels. Strategically located in Huangtu Town, Jiangyin City, Jiangsu Province, our facility benefits from mature logistics networks and a highly sophisticated machinery manufacturing ecosystem.
Relying on exquisite forging, state-of-the-art heat treatment, and precision processing techniques, we provide high-load-bearing, high-strength, and long-life transmission solutions. Our slewing bearings and horizontal rotary drives are extensively utilized in construction machinery, medical equipment, intelligent warehousing, environmental protection gear, industrial robots, and prominently, the photovoltaic and Concentrated Solar Power (CSP) industries.
As the global renewable energy transition intensifies, Concentrated Solar Power (CSP) has emerged as a cornerstone technology for grid stabilization and continuous utility-scale power generation. Unlike traditional photovoltaic (PV) solar, which depends on instantaneous sunlight, CSP plants utilize tracking mirrors (heliostats or parabolic troughs) to concentrate thermal energy onto a receiver. This thermal energy is stored in media such as molten salts, enabling steam turbines to generate clean electricity 24/7, even after sunset or during prolonged cloudy periods.
However, the efficiency of any CSP installation hinges entirely on the precision and durability of its mechanical tracking components. Because solar collectors must continually track the sun's trajectory with sub-milliradian accuracy over decades, the selection of slewing drives and swivel bearings becomes a critical point of engineering. Standard bearings fall short under the harsh loads, desert wind shear, and fine dust typical of CSP sites. It requires heavy-duty, zero-backlash, and tightly sealed components engineered specifically for concentrated solar thermal applications.
Located in arid, high-DNI (Direct Normal Irradiation) zones like the Middle East, Northwest China, and South Africa. These environments subject slewing drives to ambient temperatures exceeding 50°C and severe sandstorms. Superior dust-proof sealing and specialized high-temperature lubricants are vital to avoid abrasive wear.
Large-scale trough collectors present massive surface areas that act like sails under high wind gusts. Slewing bearings must withstand enormous overturning moments and high radial and axial forces simultaneously, maintaining structural integrity without structural deflection or binding.
Fresnel layouts require dense, compact spacing of mirror rows. High-load, low-profile L-shaped single-row ball slewing bearings are ideal here, keeping the structural profile low while providing smooth, continuous rotational control and easy integration into motorized systems.
China has established itself as the absolute global hub for concentrated solar hardware manufacturing. At the center of this industrial capability is the Yangtze River Delta, with towns like Huangtu in Jiangyin City serving as critical hubs for precision steel forging, induction heat treatment, and precision machinery finishing.
Jiangsu Manchen leverages this localized industrial density to secure top-tier raw materials (like 50Mn and 42CrMo structural steel) and advanced tooling facilities. By housing R&D, structural design, forging, heat treatment, machining, assembly, and testing within a highly coordinated regional radius, we achieve massive cost efficiencies and robust supply chain resilience. This geographical advantage ensures that global clients receive ISO-compliant, premium components at highly competitive prices, with significantly reduced production lead times compared to Western counterparts.
We provide customized designs and expert technical support to guarantee efficient, long-term equipment operations. Our production line incorporates strict quality gates at every stage of the manufacturing process:
We believe that trust is earned through transparency and rigorous verification. Jiangsu Manchen is equipped with advanced testing equipment and a complete quality control system. Our products feature complete traceability from raw material selection to final delivery, ensuring every single bearing conforms to rigorous domestic and international standards. This commitment is supported by our ISO 9001 and industry-specific certifications, demonstrating our status as a reliable partner in the global renewable energy ecosystem.
Looking forward, the global CSP sector is moving towards larger heliostats, higher concentrated temperatures, and integration with green hydrogen production. To support these developments, Jiangsu Manchen is investing heavily in next-generation transmission designs, including:
In addition, we have established long-term cooperative relationships with many well-known domestic enterprises. With stable quality and complete after-sales services, we have won wide recognition in the market. In the future, the company will continue to focus on technological upgrading in the transmission field, and strive to provide global customers with higher-quality and more cost-effective rotary transmission products and services.
Unlike standard photovoltaic trackers, CSP systems use mirrors (heliostats) to focus sunlight onto a tiny central receiver. A tracking deviation of even 0.1 degrees can cause the light beam to miss the receiver completely, leading to immediate power loss. High-precision slewing drives and swivel bearings minimize backlash and structural deflection, keeping the beam perfectly aligned.
We apply high-performance double-lip polyurethane or NBR seals to block sand and fine dust. Additionally, our bearings undergo specialized surface anti-corrosion treatments (such as zinc-nickel plating or C5-M marine-grade painting) and are packed with high-temperature synthetic grease that resists breakdown in ambient heat.
These alloys offer an exceptional combination of tensile strength, fatigue resistance, and impact toughness. After undergoing our rigorous induction hardening process on the rolling path, they achieve optimal surface hardness for wear resistance while maintaining a tough, elastic core to handle extreme wind shear forces.
Yes. We specialize in OEM & ODM customization. Our engineering team designs custom gear configurations (internal, external, or gearless), mounting hole layouts, and seal designs based on your specific load requirements, installation geometry, and environmental challenges.
Cross-roller bearings offer much higher stiffness and resistance to tilting moments in a compact footprint because the cylindrical rollers cross each other at right angles. However, ball-type bearings (like single-row or double-row four-point contact ball swivel bearings) provide lower rotational friction and are highly cost-effective for medium-to-high loads.
Our solar-grade transmission products are engineered for a service life exceeding 25 years. This is achieved through precision raceway grinding, optimal cage materials to reduce wear, and rigorous finite element analysis (FEA) to confirm fatigue resistance under variable outdoor loading cycles.
Heavy-duty options, gearless models, and cross-roller variations designed to withstand challenging axial, radial, and moment loads.
